Meet the perfect lightweight, hand-held soil penetrometer by Gilson

The HM-500 Gilson Pocket Penetrometer, also called a hand penetrometer, is a lightweight, hand held soil penetrometer

This lightweight, direct reading penetrometer provides instant estimates of unconfined compressive strength of cohesive soils. The scale corresponds to equivalent unconfined compressive strength in tons per square foot (TSF) or in kilograms per square centimeters (kg/cm2). This type of penetrometer is specified by OSHA for soil strength estimates with evaluating stability and safety of trench excavations.
